ABRASIVE AND POLISHING STRIP HOLDER.

Specification of Letters Patent. Patented Mmm'. 27, 191,7.

Appueauon filed June 1e, 191e. serial No. 104,375.

To all whom 'it may concern:

Be it known that I, Ilnwann J. MALoivnY, a citizen of the United States, and a resident of Long Island City, in the county of Queens and State of New York, have invented certain new and useful Improvements in Abrasive and Polishing Strip Holders, of which the following is a specification.

rIhe invention relates to improvements in holdersor means for mounting abrasive or polishing material, generally in the form of strips, such as sandpaper, emery cloth or the like. It has for its obj ect to provide means whereby various lengths of strip of the desired width may be quickly and positively attached or detached respectively to or from the holder and be securely held thereby. The invention has for a further object to so construct and arrange the holding means for the strip that the fo-rmer may be readily adj usted to take up any slack in the latter` The nature of the invention will be best understood when described in connection with the accompanying drawings, in which- Figure 1 is a frontl elevation of the improved holder with strip attached.

Fig. 2 is a side elevation and Fig. 3 a rear elevation thereof.

Similar characters of reference designate corresponding parts throughout the several views.

Referring to the drawings, 10 designates the base or body portion forming a backing for the holder and the face of which is preferably roughened and ldesigned to support a suitable strip 11 of the desired length and width, as employed in the abrazing, polish ing and finishing of surfaces. To retain this strip upon the base 10, which latter is herein shown as consisting of a channel member, the outer end of the strip is arranged'to be brought over the corresponding end of the said channel member and locked to the back thereof, being retained between the said back or body portion and a jaw or4 clamp 12, which is pivotally mounted between the two walls of the channel. The jaw or clamp 12 is in the form of a T-lever whose longer arm 13 is provided at its free end with an ex`- tending cam lever 14, whereby the cam portion thereof may be rotated to engage the bottom of the channel. This eects the raising of the arm 13 and correspondingly depresses and locks the jaw or clamp member 12 to securely hold the one end of the Strip 11.

At the other end of the holder, a somewhat similar arrangement is provided, the inner end of the said strip being laid upon the in clined surface 20 of a sliding member 21, whose under side is designed to slide upon the face of the said back or body portion 10. The said inclined surface recedes substantially from the said face, and is arranged t0 be engaged by a corresponding jaw member or clamp 22, mounted over the member 21 to securely hold the end of the strip llbetween itself and the inclined surface 20. J aw 22 is provided with a slot 23 through which projects a lug 24- of member 2l. On said lug is pivotally mounted a clamping cam lever 25, by means of which the said j aw 22 may be locked to the inclined surface 20 for the purpose of holding the inner end of the strip 11. In order to adapt the holder to various lengths of strips, member 21 is provided with side pieces 26 turned over the walls of the channel piece or base 10 toslide thereon, and retains a clamping lever 27 by means of which the said member 21 may be locked to the base 10. Member 21 may thus, with the inner end of strip 11 firmly secured thereto, be adjusted longitudinally with respect to the channel or base member 10 by sliding member 21 with its turned-over side pieces 26 on the channel member to take up any slack and draw the strip taut. When it is desired to remove the strip or to substitute a new one, this may readily be accomplished by simply raising the respective cam levers to open the corresponding jaws. rIhe disagreeable and wasteful methods heretofore employed for securing strips are thus done away with, and a strip of the desired length only quickly secured and held perfectly taut.

I claim:

1. Means for mounting and holding abrasive strips and the like, consisting of a base or body portion providing a backing for the strip; a pivotallysmounted clamping jaw at one end of said base adapted to hold a strip thereto, and'means to lock said jaw to securely retain the strip; a member adjustably mounted at the other end of said base and having an upwardly-projecting lug; a clamping jaw piece mounted over said lug to secure the other end of the strip to the said member; and means to lock said member and jaw together, the said members being adjustable as a whole with respect to the base; and means to.lock the same in adjusted position to hold the strip taut.

sive strips and the like, consisting of a channel-shaped base, over the face of which is adapted to be mounted a strip, one end of same. being turned over the end of the base, the Walls of the channel member at said end beingV cut away; a Vclamping jaw pivotally mounted -in the Walls of said base, and means to lock saidrjavv to the base to clamp the turned-over end of the strip; and means adjustably mounted With respect to said base to secure the other end of the strip and lock the same With respect to said base to hold the strip taut.

3. Means for mounting and holding abrasive strips and the like; consisting of a channel-shaped base; over the face of Which is adapted to be mounted a strip, the outer end of same being turned over the end of the base7 the- Walls of the channel Vmember at said end being cut away; a T-shaped clamping member pivotally mounted in the Walls of the channel, the head of the T being adapted to engage the turned-over end of the strip to clamp the same to the base, and al cam lever engaging the leg of the T to e'ect the locking of said strip; and means to retain the other end of said strip and lock the same to the base, comprising a sliding member adapted to move on the face oi the base and provided with a lug and with sides extending over the Walls of said base; a slotted clamping membel` or j aw piece mounted over the said lug, and means pivotallg;7 attached to the lug to lock said jaw to the said sliding plate to retain the other end of the strip; and a locking lever engaging said sliding member to lock the same to the base to hold the strip taut.

Signed at New York in the county of New York and State of NewY York this 14th day of June, A. D. 1916.
